Adding a second heating zone


my name is Ben and I'm new to this forum, willing to learn more about boilers and heating

I'm trying to add a second zone to my house to heat up the basement, and I ran all the necessary pipes all around the basement, but I needed some help with wiring the zone valves.

my boiler is an arcoleader that is used as both a house heater and a water heater. I'm attaching a picture to give you an idea of what I have.

I'm planning to cut the pipe coming out of the boiler and then add two zone valves in parallel. the zone valves are Taco 3 wires valves. I found this diagram but I'm not sure where the T & T wires go. how do I connect these valves with all these aquastats if I'm not mistaken

any help is greatly appreciated

The 3 wire zone valves use terminals 2 and 3 to signal the aquastat for a heat call.
